Summary:                    Partial writes on Manager API
Description: 
Sometimes writing manager events with ast_carefulwrite in manager.c only
results in a partial write i.e. not all data is written to the socket.
There is no check for this and no code to send the missing data. As a
workaround increasing the writetimeout in manager.conf mitigates this
issue.
See
http://jira.reucon.org/browse/AJ-174?focusedCommentId=10522#action_10522
for details.

Introduce ast_careful_fwrite() and use in AMI to prevent partial writes.

This patch introduces a function to do careful writes on a file stream
which
will handle timeouts and partial writes.  It is currently used in AMI to
address the issue that has been reported.  However, there are probably a
few
other places where this could be used.
